I got the AT&T Trek 2 also known as ZTE K88. It works well and is 149.00 outright or 99 cents with 2 year contract for 10.00 a month which includes LTE connection. 16gb storage and 2GB of ram. the 2 GB of ram is what I was most concerned with. I wasn't sure I needed the LTE or not but its nice to have. Solid tablet so far.
How is it going so far for you with your trek 2? Any issues using it with your solo? Thinking of getting this also as price right now is economically better than google nexus.
