should I get an LSD if I swap?

I considering getting a B16a2 for my 92 civic LX.
hybridautomotive.com sells complete swaps for about $2100 with the option of throughing in an LSD for another $300.
First off, does anyone know if this place is legit or if there is a better deal out there than $2100 plus shipping?

secondly should I go with the LSD? I've heard great things about them from people on VWvortex but they are all being used on cars with VR6 engines that make alot more torque than the B16a2.
Would it be better to just get a quaife or peloquin at some point down the road? or just skip it all together

to me, $300 seems like a good deal but not if it's going to blow up on me

thanks
