@derbear54 pretty much every gun is reasonably priced in GTA Online though, once you hit the required level and had say... $100,000 you could get pretty much any gun and a couple hundred rounds of ammo atleast.
Rockstar possibly being blatantly greedy even though EA, Activision/Blizzard and Bethesda have all recently been put up to the firing line for doing similar things... that's a bold move Cotton, lets see if it pays off for them.
Fast travel does not need to be unlocked, stagecoaches are all over the map and just cost a few dollars (there are actually more stagecoach locations in online than there are in single player). The unlock you are talking about that you unlock at rank 65 is a free fast travel system from your camp. You can still ride into Blackwater and fast travel to Saint Denis for a few dollars from a stagecoach even without that.
I have only played for about 30 minutes or so today (first friday). I have noticed that golden bars are hard to get, but the real currency (and ammo) is easy to get, especially if you do loot bandits. The missions even though does not give a lot of money, are really quick so you can do many in a few minutes.
