The acessories will be the ultimate deciding factor really. The tools and items he includes will all be items you wont have to buy again later hopefully. BP is a good name as you know, and excess rust or looseness should be avoided if you want to go to work immediately. If you dont mind a little resto work then bid what you are comfy with. I would get the pics and the list, deduct 1/2 the prices of the tools and equipment included and see where you end up. Depending on the list you could end up quite well or over priced, it's a crap shoot till the list comes. Hope you get what you want and can make some chips soon.
