Cheers for the comments guys!
Twinfan, it probably cost just over £400 in total I reckon. At first i tried to keep the cost down but then thought if im going to do it I might as well do it properly and so slightly better parts.
The main costs are obviously the body and neck and the pickups. In the UK, bodies and necks are stupidly hard to come by i found. I got the neck on eby for about £90 and the body from an online classifieds for £100 which was pretty lucky, i dont think i could ahve got them cheaper anywhere. The pups were £125, but thats one of the parts where cost could be scaled down.
_tom_, I'd say go for it, the only tools you'll need are a drill, a soldering iron and some sandpaper! It was simple but time consuming to build, with the finish obviously taking the most time, its owrth doing a good job though as it can make all the difference.
To both of you id say do it as it was a lot of fun and you can have something that is EXACTLY to your specs which is always a winner!!
