CO, WY, CA, OR, and WA are preference point states and UT, AZ, NV, and KY are bonus point states. MT you need a preference point to earn a general tag and then you can use your bonus points for the limited entry tags if you win in the first round. UT and AZ use a combo of preference point/bonus point system for a percentage of their tags, even though they're considered bonus points.
If you're asking for the states that you can just buy a preference point without paying for anything else, than WY is the only state. If you include bonus points in that question, than that adds MT and I think KY.
IMO best bets are WY and CO. If you are willing to drop $200 a year per state and understand you will need well over 20 years, and fees will increase during that time, then consider Utah, AZ and NV - if you are bowhunting. If rifle then plan to wait at least 30 years in those states.
WY and CO can get tags in a decade or less - good tags also 20+ years.
MT is easier to draw but you need a good "in" to find a decent place to hunt. The best hunter I know struggles to find any decent bull - ever, in MT during rifle season. He is in the outdoors almost 24/7
