I believe it depends on your expenses contra income. If you can't afford it, you can't, if you can, I think you should.

18 months ago I quit my job making software for Autonomous Underwater Vehicles (AUVs). Pretty interesting product IMHO, but my professional satisfaction was close to zero.
Inferior architecture, poor development processes, etc. IMNSHO...

So after about 8 years in that business I gave up. I took a cutback and changed job to something with a higher degree of professionalism. After 18 months I still do not regret that decision!

I must admit that I sometimes miss the missions (high coolness-factor++), but I will not switch back and loose the professionalism I feel today.
