[Dealmaker]

Just purchased an 03 H2 and I'm looking to install the Magnacharger. Was wondering who had the best prices on them. Cheapest Ive found is $4900.00 but Ive read some threads where some of you guys paid in the low $4k range. Any help would be appreciated. Thanks!\
Also, for those of you with the Magnacharger, is it better to use the programming that comes with it or to go with the predator? Thanks in advance!
