I have bought a few items from Evolution in the past, boots, rangefinder stalk, jetpack decals and knee armour. To be honest, the boots are ok, but the other bits I wish I had not bought. The jetpack decal was way too small, (correct size obtained from lucksy31) and the knee armour is way too flimsy and the paint job had to be redone.
So, don't waste your time lad. Go for Bobamaker every time. If he can't do a particular item, search elsewhere and only go for those recommended on this site. Daz's stuff is the best and the chap is a delight to deal with.
