Which pump for my 190g?

[MikeP]

I'm in research mode for a pump for my 190g. I would like recomendations including models and prices if possible. The tank will have a sump and I can go with either a submersible pump or dry pump. I'm still a newbie so please include any info you think is helpful. I'm not made of money but I also don't want to buy junk.

Thanks for any replies

PS I will consider buying used as well
