tranny with lsd question.

So my gsr tranny is about to go, grinding in several gears,etc.
I want to get something with LSD, I dont know if I should rebuild this one and buy aftermarket LSD, or buy a used Type-R tranny that comes with helical lsd.
what other kind of lsd's are there?
which of my two choices would be cheaper. I saw that typeR tranny on ebay for 1200 but I dont know what it costs to rebuild and get an aftermarket LSD. please help.
Thanks!!

and here they are with LSD already in them (GSR, and Type-R)
other than that i would keep looking on ebay till a good deal comes up and go for it and hope it isnt an already bad tranny

Just het a ITR tranny for better gearing and traction.....
