First welcome to T-net
Your question has been the subject of numerous threads on T-net over the years and you may be able to find some of those threads.
Most people will probably tell you that's a pretty low price range but I personally think its the right place to start. It's not so low that you cant get something decent and not so high that you will wind up with one too complicated to begin with or heaven forbid you decide you don't like detecting, you aren't out much money, and really most detectors sell used for not much less than new although if you are thinking about saving a few bucks by buying used remember that in most cases used means no factory warranty.
A lot of people start with the Garrett ACE 250. ($212 on Amazon)They all seem to like it and Garrett has great customer service.
I started with the Fisher F2 ($200 with one coil, $215 with a 4" & 8" coil plus a basic pin pointer, $275 with 4" & 10" coil, they also have an 11" DD coil available) I don't know about Fishers customer service because I haven't tried to use it yet. I got the F2 because it had decent depth for a lower end detector but is very simple to use and for the price of the ACE came with an extra coil (good for high trash areas) and pin pointer. In under a year I found enough with it to justify upgrading my pinpointer to the Garrett Pro-Pointer ($127). I also found enough to pay for a Garrett AT Pro ($600 ish) but I'm waiting for one more big find before I make that leap.

The AT Pro has been another source of heated discussions here too.
All of that being said I really like my F2. I get good depth, although not the kind of depth more expensive detectors get but I can get a dime at 6" and bigger stuff like aluminum cans at 12" or more. It pinpoints real well and seems to find whatever is there. It didn't come with headphones and they really are important but I found a pair cheap at a thrift store with independent volume control which is important because the detector itself doesn't have volume control (I don't think the ACE does either)
Guess that pretty much covers everything I have to say
