A little help-out, here?

Okay, I need some advice. I'm trying to decide whether to apply to grad school this summer (meaning that I would go after I got back from Austria) or wait until after I get back to apply.

The advantages of applying: I get through with the Ph.D sooner, I like school a lot, GRE scores still valid, able to get better recommendations.

The advantages of not applying: I have a job that I like lined up for when I get back, I would live in Houston for another year, I wouldn't have to take the GRE subject test in Vienna this fall.

Any advice you can offer would be gladly accepted, if not followed to the letter. Thanks.
