AS for lighting stuff I think JL is a bit on a the expensive side
for example from
www.lampsnow.com I got a 4bulb VHO electronic ballast set, with harness with bulbs, and reflector, with shipping (via US Postal) and taxes just under 500 bucks.
JL's similar non brand specific 4 bulb vho system costs 619 without taxes and bulbs.
I see a savings there.

P/s I think that 170 IceCap price is also with the wiring harness which isn't included at JL. Just my 2 centonies
