After doing some research, I found the best price (that I could find ... and I would be surprised to find something cheaper). At DataVision (www.datavis.com), I found the ET-73 for the price of $37.47 with shipping about $5-$6. I also got $5 off with the coupon code DATAVIS5 (which I found at www.RetailMeNot.com). I just got it today and I'm looking forward to getting some use out of it very soon.
I hope this helps someone save some money! Spend the money on good meat and choice wood!
