My friend has the SLR-105, and it isn't very impressive. The TM one, is very reliable. But a wood kit would be nice, and definitely a better spring. And for about $30 more, you can get the G&G RK47 which already has wood (Stock/Grip/Handguard ), and is pre-upgraded. I already posted all the info on it, which can be also found on WGCshop. IMO It's the best choice as far as price and quality. I would wait though, for some reviews. Just incase there is something wrong with it.
