If you're worried about cash then one of the cheaper WMR headsets. If you've got a little more cash to spread around then almost certainly a Quest. It gives you access to fully wireless play in native Quest mode (This is it's own environment/store and runs different applications/games to desktop VR, though many titles are copied across) and also optionally the choice to connect it to a capable desktop computer or laptop and use it as a fully-fledged PCVR device, with access to all the normal PCVR stores. (Even better, many titles which are on both stores only need to be bought once and are available natively or while link'd. Though do check this as it isn't every title)

Please avoid the cheap mobile VR solutions as they will put you off.
