Model 102 Tablet Rom image?

ROM image that I'm trying to find for a Model 102 Tablet. This is all new and strange to me I have but little experience on android, so thanks again for your assistance.

The Motherboard: m102_v.1.2

Model M102
Processor: Allwinner quadcore A33
Android version 4.4.2
Firmware V2.0
Kernel 3.4.39
Kernel version lxl@newqihao # 19
Monday Sep 15 15:01:21 CST 2014
Build No: astar_m102 eng 4.4.2 KVT49L 20140915 test_keys
It has an 8723BS wifi chip

I can get the tablet to run "sort of" with A33_U102_U1021C.201401013.img from "mytabletguru.com/allwinner-a33-firmware-and-tool/ " but there is no wifi. I have tried to modify the system configuration file for the U102 image file, so as to try to turn on the wifi chip, but without success. Any help appreciated.

Which V10 model to buy?

I have the choice between F600 S/K/L, H962 and H961 models.

Which one would probably have the most chances of active ROM development in the future?

Thanks
