Give ya a few suggestions! Andis AGC Single-Speed Pet Grooming Clipper | PetEdge.com
We don't usually buy these since they are single speed, but they are great and are veryyy comfy in hand. I've had a pair like them that was the 2 speed model. Andis Plus+ AG 2-Speed Pet Grooming Clipper | PetEdge.com
These are our FAVORITE at work, they are light weight, comfortable in hand, and they last us quite awhile and we shave 5-10dogs a day each with them...They are a little more pricey but I bet they will last you forever for what your doing. I probably wouldnt recommend doing full body trims with them unless you can take time and let them cool off maybe after one side haha. Wahl Arco SE Limited Edition Cordless Clippers | PetEdge.com
I swear these used to be cheaper....but they are smaller and cordless...I know you said you didnt want cordless but we have a pair of these that we use on the big dogs we do on the floor for their pads lol...they work GREAT. We've even dropped them tons of times, the blade maybe falls off or battery comes out but they last us a few years usually.
If you want something cheaper, I'd say probably try something Andis brand. I do love Oster but Andis just seems to usually be lighter and more comfy in hand. I've never been a huge fan of wahls besides the little cordless clippers I linked... Andis Easy Clip Clipper Kit | PetEdge.com
Those don't look too bad, and comes with a 10 blade, and if it dulls you could just buy a new 10 blade for 15-20 bucks or send it to get sharpened.
Ehh I don't really see any little ones I like too much, they just look cheap or dumb with the little mini blades...If you can afford to I'd just spend the money on one of the nicer pairs and have a pair that lasts you years and years lol
