@Apache is accepting orders again on 8/12/19. Best just to buy from the source for a China Clay. Once in a while you'll see a set go on sale here but you won't get much of a break in terms of price. Maybe 10 cents less a chip? Otherwise it's a really good deal unless the chips are in horrid collection.
I have a 1000 chip cash set that I'm putting into play next weekend. I'm probably going to use it as my staple cash game set because even though I've bought 800 Paulsons chips of varying designs since joining a couple of weeks ago, I'm only going to bring them out for play in very special games (maybe 3, 4 times a year max?).
What kind of stakes do you plan on playing? Your chip breakdown is good if you're playing a 25/50 cent game. Even then, I would invest in more $1's and $5's if you plan on playing anywhere near that ballpark. The Majestic line only has $20 jetons which are out of stock as of now. Hoping Apache gets more in though! The green $25 chip is my third favorite in this set though; it's not a bad thing to have a few $25's laying around even if you have a game with a low buy in. Never know how high re-buys will end up going.
Hope I helped in my semi rambling,/incoherent response!
