If you can get one for $700 off, it makes sense. Paying $2300 is tantamount to insanity. These aren't bad treadmills, it is just a case of pricing going bad along with a bad economy and a limited number of dealers.
If you could get it for $2k, we wouldn't fault you for buying one. They certainly make a nice machine but if Tunturi wants any kind of presence in the US market, they need to start aiming for the $1000 price point, not the $2000 price point.
