We have bought several PRS 2.2 stands after having used first cheap chinese stands then portable Park Tool stands which we still use for events or when we have lots of volunteers. We also have a double headed Unior stand but this is not as well made as the PRS2.2 If you are not in a hurry look for a used PRS 2.2. We bought our first one on Gumtree which is our local version of craigslist. It was over 15 years old and the only sign of wear was on the rubber grips which are replaceable. PRS2.2 are basically volunteer proof as everything is heavy duty metal.
We bought half inch plate and had the dealer bore and counter bore the holes by bringing in the stand as a template. This is important as one of the 4 holes is slightly off centre so that you get correct directional alignment if you are copying the original plates. Cost including drilling was around $100 US and the cost of labour in Australia is higher than the U.S.
We like double headed stands as it allows experienced volunteers to continue with a project while also assisting a less experienced volunteer when they need advice.
