It All Depends...
What are your goals down the road? SWA? Any Airline? Corporate?
There are companies out there that offer a Citation type rating for about the same price as a 737 type. I don't think having a 737 type carries the stigma that it once did, simply because of the turmoil many airlines are going through today. Now, 10 years ago I know for a fact that a 737 type on your resume would be a negative when applying for a corporate job (other than one when the company has a 737). Same went for an FE rating. It was assumed that the airlines were your career goal.
Any type rating without time in type isn't going to be of much use, especially considering insurance requirments these days. Yes, it says you're able to pass a checkride and earn a type. It might get your resume in the door especially if the operator has that type of aircraft. Personally, if you have that amount of money to use towards a type and aren't currently flying regularly, use the money to rent a light twin and stay current. You'd be much better off down the road when you're ready to return to flying by having stayed current and gotten another several hundred hours than having 10-20 more hours and a 737 type rating.
To each their own, but I'd rather fly a light twin once or twice a week than add a 737 type to my certificate with little hope of ever flying one (since I have no airline desires and BBJ jobs are nonexsistant in my neck of the woods).
Good luck with your decision.
