Well the great thing about living in the USA is that there are many options to explore.
Hopefully if there is some form of walk in retail hobby shop that carry's airsoft, you could pop in and have a look and handle some of the hardware to see and feel what the differences are.
Modest quality spring pistols usually start around the 20 dollar area and go up from there. You can even find gas pistols in CO2 or propane starting at around 40. In my opinion its worth the extra investment to go gas over spring. With spring guns, you will have to manually cock and chamber a round to fire every time. With gas its just pop pop pop reload when the mag is empty.For the most part, spring pistols cannot be upgraded, while many GBB pistols can be upgraded.
