Alrighty mate, well, if those are you favs, then the G36 will be cheapest for ya. I love Tars as well, saving for one now (even though I just bought an MP7 and may be moving in a few months... A big thing to keep in mind; until you get registered with UKARA (oh no I've said it), which is easy to do, you can only buy guns that are not RIF (realistic imitation firearms), which means you can only buy two-tone guns. Not recommended, as you should just rent; if you get a two-tone, and you end up not liking our little game, it's harder to sell a two-tone gun, as fewer people want those. Also, if you buy and and DO like the sport, once you get your UKARA registration number you will be able to buy RIFs, and will never use your two tone again, no matter how much time, care, and cash you've put into it. So I say go rental at least 3 times, get UKARA registered, and go from there.
