I've been thinking of getting a wormery for a while and have just noticed a couple of sales. Does anyone have any pros/cons they could tell me about? There are five of us, so I'm looking at getting a largish one. Cost is less crucial than efficiency.

These are the sale sites I've been browsing:

Wormeries - Bestselling Wormeries from the Wormery Inventors : Original Organics Ltd

Wormcity Wormeries Winter Sale Now On

Info on other sellers welcome of course! I know you can make your own but I'd prefer to just buy one really!
