None of us need a skimmer..... It defiantly helps all of us though. You can do without but you will have to do more pwc to keep your water in check. With 1 fish and an anenome your bioload is quite small. If you did get a few more fish It wouldn't hurt for you to get a small hob skimmer
Skimmer is really nice to want for your small tank. Definitely not needed though. You can get better water quality by doing more water changes. The cost in salt will be proportionate to cost of buying/running a skimmer.
I've run small tanks with and without a skimmer. While a skimemr is a nice piece of equipment to have I don't think it's a necessity. If you do say 3g a week in water changes you should be good to go. The anemone does concern me though. How long has the tank been up, what are your parameters now and what kind of lighting do you have? Any money you might want to invest in a skimmer might be better spent in relation to the questions I just asked.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
