2 pole tester measures voltage and continuity. Fluke are reliable, but there is four in the range with vastly different pricing. T90 is basic, but does the job perfectly well. T150 is top of the range, with phase rotation if that might be useful.
Multifunction testers start just above your budget with the DL9110. I have one and it works perfectly well, covering most functions you'll need. Some folks don't rate them, although few have actually used one. Top end of MFTs will set you back £2k, with quite a few extra functions, including EV if you need it and wish to buy extra attachments.
