What is "reasonably priced" to you?
For the beach (dry sand) and the dirt just about any machine will work - some might work better than others though.
For wet salt conditions the price goes up a bit if you want a machine that is waterproof.
A new Nokta Simplex can be had for $250 (without the wireless headphones). Adding the headphones moves the price to $330 or so. Most reviews are very positive. Not ideal for salt water hunting, but it is waterproof and can do the job if hunting the salt water isn't the primary goal.
The Minelab Vanquish 440 can be had for $270 or so (new) and it will do fine in the wet salt sand. It isn't waterproof though. Most reviews have been very positive.
The most recommended machines (for general hunting - including salt water) are Minelab Equinoxes (either the 600 or the 800). Both are waterproof, both have lots of positive reviews. The 600 runs around $650 new, and the 800 runs around $900 new.
There is also the Garrett Apex - around $400 without the wireless headphones ($480 with). Like the Minelabs above, it is a multi-frequency machine. It is not waterproof though. Very good on wet salt sand.
Nokta also has the Multi Kruzer and the Anfibio (multi) - both machines are waterproof and both let the user select the single frequency from one of three available frequencies. Both are very capable machines, but hunting wet salt sand isn't where they truly excel (they can do it, but you won't get the depth/stability of a simultaneous frequency machine). The Multi Kruzer runs somewhere around $550 new, and the Anfibio is another $100 or so.
If you ask your question in the general forum, you'll likely get a lot more replies/suggestions.
