If your ship gets shot and disabled, its not destroyed. You need a crit for that. So your players aren't killed for their trouble.
You might want something that fits an astromech droid, the extra actions and aid with piloting can be invaluable.
I wouldn't crawl into a fighter right away. I think they need a tad more experience or characters that aren't that good out of a fighter.
Grimmshade: Speeder Bikes are hard to take out with hand held weapons, but it can be done. Auto-blasters trash them fast.
One other very very important consideration is that your players can customize and make their ships more resilient. My players upgraded and super heavily modified the shield on the YT-1930 (equivalent ship). When they had the upper hand in the combats, the extra shielding made it impossible to harm them.
They captured quite a few Speeder Bikes on Cholgana and they've been modifying them (and filing off serial numbers). The most popular mod is armor which makes it really hard to put a dent in the bikes with hand held weapons.
PS. Don't forget to get your Slicer to disable enemy fighters. They inflict strain and fighters tend to be weak. (Now that does not fit the movies at all. Wouldn't you hire 100 slicers to wipe out the entire opposing attack force? "Ha ha! I change the admin password on the Death Star to 'VaderBl0wz'!")
