I found this website which matches my experiences pretty closely
Pick one that's under budget and read the reviews, IMO MAC is good

I use pic related, the Lansky one, honestly one of my best purchases
There's a lot of brands, you could even buy 2 rods and build your own
Whetstones have the best performance/cost ratio, but needs more skill
I tried stones before the sticks, not hard if you practice sharpening often
There's also the rolling sharpeners, but the good ones are expensive
