couple hundred bucks for shipping is to loose ... if the part is bad they'd send just that ... now assuming they actually give you a replacement of the broken part ... they dont warranty like tps sensor and stuff which is commonly broken and if they do i've heard they are anal ..
They caught my eye because they're in Canada so I wouldnt have to pay duty ... I read up on them and they said even after months they aren't getting replacement parts, or they dont respond but otherwise really ****ty service... they just want to move in bulk and sacrifice customer service for profit and sell high numbers...
Heres a few sites I bookmarked that sell engines:
(One of them actually did a leakdown on an auction that sold on ebay (entire 4gen front clip) for $2600 190's all accross w/ lsd)
