serger and sewing machine?

[velvets.livejournal.com]

i am toying with the idea of buying a serger. i have a regular sewing machine that it having issues due to water damage (ugh) and am wondering if there is such a thing as a serger that can also be used as a regular sewing machine? i don't know if this exists, due to the nature of a serger, but hey you never know.

anyway, any reccomendations on sergers?
or (hopefully) on sergers that can be used as standard sewing machines?

Thanks!
