If you are going to buy slugged ABS, I think you have found the style of sluggos I think are the best, the Outlaw, Lucky Horseshoe, Monaco bunch.
The basic progression is: Dice chips -> other slugged chips -> china clays or ceramics -> casino clays or casino plastics
That said, I recommend you skip the sluggos. Most folks end up getting casinos eventually. Some stay at the china clay or ceramic phase and are happy there. But virtually no one who spends a lot of time collecting chips is happy with or stays at the slugged ABS stage. You can get china clays or ceramics for just a bit more money, especially if you shop deals in the classifieds. You will probably not be able to sell the sluggos in the future, but there is a market for used china clays and ceramics with good designs and in usable breakdowns.
Here is a deal for a base of Pharoah china clays:

You can buy another rack of $5s and a few barrels of $25s off of
Apache to complete it. Or post a wanted ad - you may find someone with extras they are willing to sell to you for cheap to help a new chipper.
If you like the Outlaw design, the the
Nevada Jack ceramics from BR Pro Poker might interst you. I have some 25c chips coming my way that I don't need. I can send you a rack for the cost of shipping ($10) just to help you out. Then you can get the other denoms from BR Pro.
One last thing to think about: security. Stock chips from any retailer are insecure because someone can bring in chips into your game and slip them in. The best way to avoid this is with custom chips. But that is mostly out of your budget right now, but you still have options to customize:
1. Custom label a sluggo or china clay set
2. Go with a Tina ceramic group buy and use a custom design
3. Buy a custom china clay or ceramic set used from someone that is unique
4. Not as good as the above, but another option is to go the "semi-custom" route with BR Pro. They will change the denom colors for you for 5 cents more per chip. It is not as good as fully custom, but makes it a bit more effort for someone to sneak a chip in, because they'd have to go place a semi-custom order themself.
