I bought one from the Harbor Freight store. They were in sale for $199, then I used a "20% off" coupon for a total price of $160 + tax. Adding $19.99 for the 2 year "replacement warantee" got me out of the store for a total of about $188.
This thing works great and has really come in handy during the restoration of my 1969 Pontiac GTO.
