That's a decent price when you add up all the costs involved.
Racepace have a strong following on here, for good reason.
Add up all the costs of buying parts, machining, assembly, motor R and R, run in, tune etc and you'll probably see (like a lot of others) that a decent build can cost 8/10k without too much sweat.
There seems to be a lot of newcomers to these forums who believe a rebuild costs a few thousand, probably due to the cost of the rebuild kits out there. Then they find out the hard (expensive) way that they were wrong.
IMO, do it right the first time, then there's no second time. Works out cheaper than two budget builds not to mention FAR easier to just tow it to Chris, wait, pay then drive home once it's all done.
Goodluck with whatever you end up doing
