Brunswick Gold Crowns IV or V
Just to let you know (you might already know), Brunswick tables (new) are sold exclusively through retailers and the mark-up is rediculous. 8-9k is rediculous for a pool table in my opinion (unless antique maybe). You are always better off buying a used table, maybe a gold crown IV from a pool room or someone liquidating one. Billiard clubs like me can get brunswicks at at the same cost as the retailers $3500-$4000 and you could get a table in great shape from one of them maybe going out of business.
Diamond on the other hand, sells directly to the public. You can get a Diamond pro-am for the same price as I can. I recently bought one for my billiard club and turn-key (shipping, balls, diamond light, rack, setup, etc) I spent around $5800. Personally as a player I like the Diamond the best, for looks, durablility and playability.
But if money isn't an issue than it doesn't really matter, you probably would prefer a new brunswick over a used for the convienance. Either way both companies, Brunswick and Diamond, build there tables to last a lifetime. I have yet to see a Gold Crown IV in bad shape, or a Diamond Pro-Am.
Hope this helped, good luck.
