I wound up making my own a few years ago so that I could incorporate automatic valves. (I wound up with an ugly jurry riged stand that I still frown at when looking at it... from spare parts... and put the money I was going to put into a stand... into valves and PLC controls to automate the brewing process)
When I was dong my stand research though....
From a brew stand...standpoint. I was going to go with the Ruby stand. The stand is powdercoated... so the paint is much stonger and robust than a typical painted stand, (and like the stainless stands.. it will last "forever") and I Iiked the design for mobility, and conviently tipping for compact storage. The valves being accesible for the gas was a big thing for me, and the Ruby Stands are really set up nice to allow future expansion... and was just setup in a way that made adding a piece here or there as time goes on easy. The frame has more places to bolt things onto, and looked more robust. Since then, I noticed the local brew pub uses these stands for their brewing.
They went with them because the guys making the Ruby stand were really easy to work with to put the bells and whistles onto the stand just they way they wanted.
Having said that, with what I know today... I would NOT go with the base burner package of the Ruby system. The base burners are not really conducive to converting over to natrual gas. The burners on the Synergy system are. (my old brew satand had the ruby style propane burners... and they were LOUD, and were not able to be converted to natural gas... my new brew stand, I made with burners simlar to what is in the synergy stand. They are far quieter, I would even say silent, they put out more BTUs evenly under the kettle, and I have since made them Natural Gas) I know the brewpub has burners like the synergy stand on thier Ruby stands...so I know Ruby offers them.. but I dont know what the price difference is.
Good luck, hope your new stand, whatever directin you go, brings you many happy brew years!
