Novo7 Aavanced was supposed to end production last month, but the International sales was so good that Ainol made another 1000 sets earlier this month. Not sure if the 1000 were sold yet.
The reason is Ainol has plans to expand its Novo7 series for Q1 of 2012. On slatedroid someone mentioned that there'll be a IPS screen Novo7 out on 5th Jan. He mentioned the source came somewhere on Merimobiles. So it's still a rumors, as the earlier rumors was that the new Novo7 tablets will be in around Feb 2012.

Gemei G2 is the 1st 7" 1GB RAM Allwinner A10 tablet I know of. 1GB RAM does seems to improve the performance of Allwinner A10. However it has a shortcoming similar to P76Ti, and that is the 3200mAh battery. The actual usage might be too little. which is about 3.5-4.5hrs.
P76Ti is one of the hot Allwinner A10 favourites in China. It's along side with Onda Vx610W. The reason is mainly due to their cheap price, which is 499 RMB. Onda Vx610W lacks HDMI though.
As for Xburst (Novo7P and Novo7B) I would avoid till they improve the apps compatibility. Allwinner A10 is a better choice due to it's video capabilities, but it's not the best choice. Especially so with newer dual-core tablets coming out in Q1 of 2012
LY-F1 is from the same company who makes GTPad, which is LYXZ. I think it's more like a Shanzhai company. It's supposed to have ICS firmware update later. Problem with smaller China tablet company is always the support they give.
Based on your write out I believe you had done some research. You should be able to make a good decision on which tablet is best for u

I'm not sure how tech savvy you are, but do consider in the online community support too.
The problem with China tablets is most users are Chinese, you can't get community support unless you buy the tablets most International users go for. But if you are tech savvy, the problems you faced on China tablets could be fun to tackle with
Currently Allwinner A10 tablets with good online community is Novo7A, then Momo9c (with it's clones), then Onda Vi series. Currently I'm more geared up towards the upcoming 999 RMB 9.7" IPS screen tablets, which is Onda Vi40 Elite and Bmorn V99 deluxe/plus. These are Allwinner A10 & 1GB RAM with 9.7" IPS screen. I find them to be best value for me in Q1 of 2012
That's unless SmartQ Ten3 decides to join the 999 or 1299 price, then it'll be the best value tablet for me
Good luck getting your tablet.
