I have just recieved some torsos and bionic legs from Anvil Industry and I was quitee impressed with the quality that I though I would write up a short review of what I bought.
First off are the torsos. I bought several of just two types that I thought would fit in with my Space Wolf army and be useful with any other Space Marine projects of mine. Below are the pics.
here, and I might buy the Renaissance Torso as well.
I also blue-taced some Space Marine parts together to let you see how they fit when assembled. Overall I think they work very well.
I also bought several 'medium' bionic legs from the same company. 'Medium' sized products are for Space Marine sized models. They come as a multi-part kit that is very similiar in design construction to Forgeworld's Contemptor Dreadnought. You can consturct a pair of legs with them.
The great thing about this design is that you can build up a model with two bionic legs, or one bionic leg, or with a bit of modelling you can build half a bionic leg - either the above the knee or blow the knee. They would make for excellent Iron Hands conversions.
The company have other bionics as well. The parts designated as 'large' are for Terminators and the 'small' are for normal sized humaniods. Overall I suggest you check Anvil Industry out if you are interested in finding parts allowing for some interesting variantion for your 40k Imperial armies.
Farewell and good health
