I'd chip in the extra and go with a USA kilt or a Stillwater heavyweight wool. You've already got an acrylic kilt, no need for two if your expanding on a budget in my opinion

You've covered the "cargo" style kilt and the "budget" kilt. Personally, I'd go with a USA Casual before I'd go with the Stillwater just because it's machine washable, very comfortable and tailored to your measurements. But the Stillwater would be on order very soon after that as it's a great option to have as well.

Good luck with the decision.
