I think if you are really serious then you should get a Riley steel block table, it does not have to be the ones with the silbver legs as seen on TV.
Riley pockets are less forgiving than the other brands especially Brunswick.
If you are able to, try get the template so you can set up the pockets like the way they have it on TV.
You need to check the drop of the pocket as with some tables a ball placed on the lip of the pocket would drop automatically while on a tournament standard table it should not.
There are some snooker tables for sale from time to time in Canada, some BCE, Brunswick, old B&W, Thurston, and even Rileys sometimes. Brunswick would be my last choice.
If you can afford it, get yourself some decent snooker cloth, such as West of England 6811 or No.10.
Even if you cannot get a very nice table, get some nice cushion rubber (Northern), steel block rail, no.10 cloth, and pockets that confirme to the template, you will have a decent table to play on.
Do not use pool table cloth as it is just not the same.
