If I could spend my money again, I would go them... IF I was to go electric again - which I would.
If going gas, IMO only, I would think that the Robinox range with the thicker/sandwich base would be a better option, again my opinion only.
In short - you get what you pay for. That said, if you can only afford Ross' pots then you will still be happy, as per Truman - tradesmen blaming tools etc...
Fark it - you have me redesigning an all Blichmann rig in my head as I type.... *waves fist* - DAMN YOU!
Go with what you can afford and then push it a little more - BUY ONCE, BUY RIGHT.
