Hm, great list! Here's a few other great ones, with good first deposit offers.
Maria.com: sister to Unibet, good games, decent offer and easy and
fast payouts (i took both offers, shouldn't be a prob but check with live chat to be sure)
Redbet: amazing site really, even faster payouts and also good bonus and Game matrix * play up to 4 Netent games at the same time
CasinoLuck: very good Casino all of the above, and more NDB Free Spin offers for regular players, plus NDB and GREAT SUB
NextCasino: Sister to CasinoLuck, see above
CasinoEuro: Good SUB, very solid group (Betsson)
Thrills also has a sister called Superlenny, but don't know how they stand on taking both SUB's...
Also note that CasinoEuro and Uni and Maria have some cool exclusive games from various providers, which could be fun if you win big on DOA on your SUB
Worth mentioning maybe a few of the recently accredited Casino's, saw some good offers from those and the comments on some of them (Betspin as example) are VERY positive!
Take your pick
