If you are looking to get some interesting, fairly unique bases for your army and want a consistent theme but dont want to spend hours making bases, then resin bases are an excellent choice. Resin bases are simply casts of terrain and textures on standard sized bases made in resin (what a shock!)
Working with Resin Bases
Resin often needs cleaning and trimming but is usually easy to work with and has a similar feel to working with plastic. When gluing, do not use plastic glue (polystyrene cement), instead stick with superglue or something stronger. Some companies use a heavier type of resin which is very hard to drill for pinning, so be careful and stick with glue where possible. When filing resin be sure to do it in a ventilated area as many types of resin are very bad for you if you breath them in and it is very easy to do so when filing at speed.
For more information on working with resin bases, check out the article on Using Resin Bases.

Making Your Own
One other option for resin bases is to simply make your own. Resin casting kits can be found in many art stores and allow you to make silicon molds from your own home-made bases. You can then cast as many bases as you want from those molds allowing large numbers of similar bases to be created for your armies!
