Looking for modern used gear. How old is too old?

Current set is circa 2003.

I bought used skates from 2013 with cowling but they have a super tall aftermarket blade. Planning on trying to get by with them for now but keeping a cowling-less pair in mind eventually.

Gloves are fine I think. Mostly looking at pads. Been browsing Sideline Swap and there's some Vaughan Ventus LT88 that seemed a good value but they're from 2015. They look to be "modern" i.e. designed for butterfly but 10 years old seems old enough that meaningful improvements have been made since then.

My current chesty is toast too but those seem pretty standard albeit super bulked up from what we used 20 years ago.

Trying to keep costs down FWIW. I'm fine with a 10 year old set if they're modern enough.
