UPS on Linux

Hello Everyone....
My dad and I are looking at getting a UPS for our server, as it runs the

web page and ftp server for my diving team, It would be nice to keep it
up during electrical storms without worry. Along with any unexpected
brown-outs/black-outs.... I was wondering if anyone has experience with
them and what ones work well with linux? We are looking to keep the
budget down, prefferably under $100. Thanks in advance.
