I'm looking for a quality frog rod for 180.00 or under. I want one at least 7' that has a good backbone but is easy to walk a frog with and skip under overhangs. I sometimes throw frogs under 1/2 an ounce (ie old scum frogs), so should I go with a MH or H rod? I'll be using 50 pound braid since I don't have super thick salad around here, just patches

Here is a 7'2" heavy Tatula rod for $100 on sale. They also have MH if that is your choice. Nice rod for the money.

I have been using a Dobyns Savvy 735 for frogs for several years. You can find them around $150 on sale and closer to $120 used.

I use a Lamiglas Pro X 735. It has a rating of 1/4oz up 1.5oz and it does cover that range. I throw from unweighted horny toads to the huge SPRO frogs on it with 65lb braid and they all handle really well. The shorter butt section makes it really easy to walk without getting fatigued. It's slightly above your price point but it's worth it. 

I've read nothing but good about the Powell 735's also.

Dobyns Fury 735

Kistler Magnesium 2.

Lews custom speed stick magnum pitching stick for heavy grass.

Lews custom 7ft magnum mh casting rod for sparse cover.  Light and balanced 

I second the kistler mag.  I have the 7'3 H slop/frog.  It's amazing.  The tip is soft which allows you skip super easy but it also has plenty of backbone.  The thing is super light too.  I can frog for 9 hrs and not be tired.

Dobyns 735 or an Avid MH.
