I just got another TX-7 on ebay for $140 with turner and extra egg grid. It is on the way. Just keep looking and when you least expect it one will pop up.
I ordered Lyons TX-7 and it works great. Every time you look at it, the temp and humidity is where you left it. It holds 18 large eggs 24 smaller eggs. Very easy to hand turn if you do not get the turner. You don't have to open the incubator for anything.
