Just get a mask and then rent until you are happy with the game, want to continue playing.
A mask can resale pretty well if it is in good shape, and it really does significantly impact how much you are enjoying your time. Poor visibility and fogging will kill your fun very fast.
Don't worry about what you are using as gear. I've got guys with $1000 markers out with my $40 project gun. Kids with 20 year old rentals have got me out when i thought myself well practiced. They all shoot paint at the same velocity cap for your field.
Find some friends. Most likely they have closets full of guns they will let you use anyways :P
I like Spyders.
