Please recommend an RO unit for me...

[lakwriter]

HI all, I want to get my own RO unit. No more trips to the LFS for water for me!

I don't need a high GPD capacity, as I only need about 5-10 gallons a week.

It needs to be portable, not permenant, as I will need to connect/disconnect from my laundry tub faucet.

I can't spend more than $200.

Your help is greatly appreciated!

Ok, I've heard a lot of good things about them. I'm looking at the 4 stage 75 GPD.

I really know very little about these units. Whick of these accessories are really necessary and/or are make life easier?
PRESSURE GAUGE KIT - $12
FLUSH VALVE - $10
DUAL TDS METER - $35
DUAL DI SYSTEM - $62
SINGLE DI SYSTEM - $36
AUTO SHUT-OFF - $8

I think the TDS meter is a must, but what about the others?
