I bought one of these a few weeks ago. Still not installed yet so I could have waited had I known this was going on sale. Was $199.99 online (Fed-Ex $6.99 shipping).
I searched for an online coupon code prior to purchasing and found one for 30% off, so it cost be $90 instead of $120. I thought if it were $100, my coupon would have yielded me an engine for $70.
I can't recall where I got it, but just typed "Harbor Freight coupon code" into Google and searched about three of the links and found it. It worked great.
