welcome.. the more oldies we have on the forum the better. Yes we need toilet breaks as the old bladder gets worse as we get older but HEY? what price experience?
this forum is not a good place to buy anything, before you know it there will be 15 bats turning up with the postie before you realise you cannot possibly use them all.
Anyhow, I would start off with an ebay second hand job before you really get back into playing. Do you need a lighter bat as the old reflexes have gone a bit? yes, well I certainly do anyway..
So pick something lightish and off you go.
If you do go the ebay route and have any doubts about what you are buying just pop it on here and the forum police can sniff out a fake bat/seller-quicker than you can say 'IVA Richards is god'
good luck and welcome
