I love ny Vararam. I got it used and it was in mint condition when installed. Either way, you can't go wrong. You might also consider a 160 thermostat and have a tune and fan speeds adjusted. The vendors that sponsor this forum have excellent reputations and I would recommend checking with them for various pricing, etc. If you want my personal opinion on specific vendor, send me a pm and I will share with you who I prefer for what it's worth.
