I have a Garmin Aera 500 and have been using it through the summer, which will meet your price bracket.
By and large, I'm really happy with it. Good clear navigation, some useful tools such as the E6b, flight log and HSI page, once practiced quite easy to use as a source of reference for various data such as airspace heights, frequencies, approach aids, and so-on.
On net, if somebody nicked it next week, I think I'd buy the same again.
Also with a bit of massaging can help out in getting onto instrument approaches, and whilst not legally cleared as such, does have all the waypoints for published GNSS approaches if you need a "get out of gaol" card one day, as well as GPS guidance onto any ILS.
The extra few quid on a yoke mount is well worth it. Best powered from a lighter socket, but I can get 3+ hours out of it without so long as I'm careful with the screen brightness. Another £30 with a shop in the USA got me a lead that allows me to patch its audio warnings into my headset.
