New astro is ~£1k for 100 square meters.
2nd hand astro ~£1k for ~300 square meters, about 30/40% of the Bury track?
The Bury astro is good, it holds the and well, I wish I knew how it did
You don't need any big machinery in my opinion, just men and time. That is unless you want to rip up what's there, but I see no reason to, the track is great and many clubs would love to have it
I know how much time it takes to build a track guys, a long long time
