i would go with ro mate

[richardlingard]

you will want an ro system as well really, i have a similar tds but you will find your resin will last for ages, fill a static tank and use the small di polishing units that cost around £30 straight after you r o realistically 450gpd sounds about right, i think theres on on ebay for around 150 which is great becaus ei payed more than double for mine

Iv got about the same TDS reading as you mate and i started out with a 9lt DI vessel, then bought a 11lt DI vessel to make the most out of my resin and then bought a 300gpd RO. If i was you i would go straight for the RO if you can afford it pal
