I would encourage you to go with Marlin, or even All Pro. TG's rep, to me, anyway, is relevant. Yes, the TG kit is cheeper and has a few more bells and whistles, but at the expense of others. Not saying that others who buy the TG stuff are wrong...just saying that Marlin has always done me right and I want him to have my business. You do what you think is best.
