The best and cheapest way I found was to buy a used unit off something like ebay and just buy new filters for it,

I got a 3 pod 100gpd ro unit with di chamber and inline tds meter for £16 the the new filters were around £22

Imo no you dont need a di chamber its more of marine aquarium thing I think but dont know 100% but basically the di chamber comes into play if you have a high tds and want very low tds water again I think im right in saying as a rough example, an ro unit should remove around 95% of input so if you have tds of 400ppm after the ro membrane you should have around 8 -10 ppm the di chamber should take this down to zero,

Thats my understanding of it but I might be wrong
