Tight V. Formation

Okay, so my part-time employer is asking me to go full time with them. Now if I give up working there part-time, I'll lose about 7 to 8K a year in income. They will pay a little more than my full time job does now. The thing is, I'm not happy at my full time job...but here at Syrus, I like it... it's small and the people I work with aren't pretesious jerks. The job itself is more technology based than the Chase position as well...So now I'm kind of wondering which path I should take...
