Advice on 1st buggy - Found some rollers but unsure about $ etc

[Gee]

Thanks for all the advice. The xray isn't in the budget right now. The vet says my dogs gonna need braces as soon as I get him to stop chasing parked cars. Seems when I ask for pictures of the bottom of the buggies on ebay the buggies isn't available at that time to take any. Huh? The D8 does look like a good buy. I'm thinking I might want to go with a new one vs a used buggy. A Main has the Lightning Pro 2 evo on sale for 249. Seems a pretty good buy. Anyone seen one in action?
