If you're still considering, let me sum up. When I took a job at a similar operator in the hopes of building multi time, there were many pilots (most with more than triple my hours) that said they would never do it. I was in the job for 8 months, scraping by on the bones of my arse, but the experience overall was a positive one, and gave me the flying experience I needed to get a regional gig. Now, over 2 years on, many of those people who were once ahead of me, are still chugging round in singles.
I don't think any less of them for taking a different route, but the goal for me was not to give myself an easy ride, but to get there as fast as possible. So it really depends on what sort of person you are, and what goals you have. If you want an airline job yesterday, you really can't afford to pass up an opportunity to get that valuable multi time.
