Rebuild or New??

Been having some issues with my 904 over the past week....came to a head the last 2 days when I have no 2nd gear either manually shifting or in auto....just put a 3500 stall and a Turbo Action valve body in about 2 months ago, and it really woke it up until the problems started...the question is, do I spend the money on a rebuild, or just go with a new one? I have been checking out the Turbo Action 904's on Summit, going for just under $1K with a shift kit already in it....also looking at Performance Automatic one that's a little more...don't have a lot of green to throw around these days, as everyone else, but I don't wanna put money into something and have further problems down the road....any advice?
