Ahhh you're lucky I'm a dwarf player. I love em they are very reliable with their high leadership and runes on war machines that make them expensive but more accurate and hit harder. The dwarf battalion is also in my opinion one of the best buys if you are looking to start dwarfs for your first 2-3 battalions you will use everything. Dwarfs do not have a magic phase, however their rune system is really cool. Instead of getting a magic weapon or armor you add runes to them making them stronger, if you are familiar with World of Warcraft think of it as enchanting or jewel crafting.
GW warrior is a steal at 10 pts for a WS4 S5 T4 5+armor save. Plus while they have no magic they still use their magic phase to generate dice for dispelling remain in play spells and buffs and since they can have I think up to 3 dispel scrolls called runes of spellbreaking and a rune that takes an opponent's power dice and gives it to you as a dispel dice, on top of all this most mages need to roll a 6 in their casting phase to generate an extra dice but dwarf runesmiths get 1 automatically and runelords get 2 dispel dice, and we get a +2 to dispel all spells. Their movement is low at 3 but in 8th charges are now all Movement +
2d6 so they got a boost there. I'm going to copy and paste my guide for starting a dwarf army that is inexpensive and effective.
Try and get a BFSP dwarf set and 2 battalions.
You get 32 warriors in each battalion, make 32 as great weapon wielding warriors and convert the other 32 into hammereres see this link:
http://www.bugmansbrewery.com/topic/20562-a-converters-guide-to-plastic-hammerers/
These hammerers also can double as great weapon warriors when you need them to be.
With the Battle for Skull Pass you will also get some shield warriors you can use as filler if you need too buff units up just put them in the back.
You also get 10 thunderers in the BFSP so use the 32 you would get in each battalion to make that 20 then use the other 22 as great weapon quarrellers
In the BFSP set you also get a cannon and a pony cart which you can convert a cannon or organ gun too with the left over bitz in the battalion:

http://www.bugmansbrewery.com/topic/29204-the-army-of-droum-peak/page__p__297469__fromsearch__1#entry297469 - Scroll down a bit about 60% of the way down and you'll see it.
So for war machines you should have 2 Organ Guns and 2 Cannons
The dragon slayer that comes in the BFSP set is actually pretty good at hanging back with your warmachines and protecting them. Any light cavalry or units that turn up on table edges will get tarpitted 1-2 turns by this guy because of his high
WS and T.
The Thane in the BFSP makes a great Runesmith/Runelord as a shield is a cheap investment for a RS/RL, all you really need up to like 1.5k maybe even 2k is the Rune Smith/Lord and a
BSB, I really like
GWs bsb model but it's special order they don't carry it in stores but it is worth the 1-2 week wait.
You will also need a
BSB you can make your own with all your bitz but I love the
BSB model, probably my favorite
GW model:

You will also get miners in your BFSP set, 8 of them, you can use them as intended or stick them in warriors blocks as filler.
So there you go a solid army...
76 warriors (32 hammerers can double as warriors) or 82 with miners
22 quarrellers-work great as rangers
20 Thunderers-These guys are cool, Organ Guns generally do the job cheaper
2 Organ Guns
2 Cannons
Runesmith/Lord
BSB
Dragon Slayer
Solid start, I highly recommend picking up a Grudge Thrower as well they are the best thing in our army book when runed up. I took down 18 of my buddies blood letters even with the 5+ ward save before he reached my warrior lines,
GW warriors and hammerers are the next best thing.
I am actually working on getting some more miners for an idea I posted as ambushing dwarfs in the army list section, check it out it's not advisable for starters but kind of shows you all the cool variance in tactics in a dwarf army.
