For surface Lucky Craft Sammy 110, Yo Zuri Hydro Popper (9 cm) and Lucky Craft Gunnish/Gunfish 115 . The Sammy for the walk-the-dog (I got my first ever bass with one of these); make the Yo Zuri pop with variable retrieve speed/rod jerks and several-second stops (5-10); the Gunnish/Gunfish is something in between the other two.
For sub-surface try the Lucky Craft Flashminnow (110). Retrieve VERY slowly and I mean VERY slowly: 2-3 slow turns, stop for a few seconds (they will suspend in mid water), slight rod tip jerk, another couple of turns and so on. Make each cast-retrieve process last a couple of minutes. It's a killer plug that will catch you many fish including pollack.
They should all be within your budget but look out for second hand Japanese plugs on eBay for reduced prices. I'd choose "natural" colours like mackerel or silver with dark backs. And change the trebles in the Lucky Crafts.
Enjoy!
