Life is a gamble and taking a type rating is a big gamble without a secure job offer and knowing what type. If you got yourself a 737 rating, then what model who you go for? 737-200 is different from a 6-700NG and an 8-900NG rating (as I believe), so you take a gamble with that as well. If I were to go for a rating I'd think A320/B737 are the best bets and at an outside B757, for Europe.
I agree with the 'clan' that we shouldn't pay for type ratings, I can't even if I wanted to. It is clear to me that it helps the industry jepordise others in doing so. You've made your choice though, and sad to say but in this world people mainly care about themself, so good luck in your gamble.
