Just ordered an NX7 Pro last night from www.precisionprogolf.com, and got a killer deal! They are having a $40 off sale during the PGA Championship, and the discount code mentioned earlier in this thread gets another $20 off, so will be delivered for $209.
I've been using a TecTecTec with slope for the last couple of years, liked it fine, and worked well for a low-cost unit, except for a couple of quality issues that developed over time. The biggest problem is that ever since I replaced the original battery its really hit or miss on locking on a flagstick. I even talked to their customer support, via email, they helped me out with a parts issue (eye piece), but pretty much ignored the real problem. So, time to look for a new unit, and with so many positive reviews on the NX7 Pro, and Precision Pro being engaged here on THP, made this a pretty easy decision. Really looking forward to using it, I really got used to having a rangefinder, but have pretty much quit using my old one out of frustration with it.
