We bought an LG FL washer/dryer pair for $1K last year on a black Friday special at Best Buy. The washer is WM2301, a simple machine but it has large capacity (4.2 cf - I haven't washed a comforter in it but it handles our thick king size mattress pad with no issues). The washer also has an internal heater which was really important to me, but no other fancy features which I don't need. So far, I have been very pleased with this washer and dryer and can definitely recommend it.

The fact that the cloths are dryer from the high spin probably does effect wrinkling, but my Cabrio has a high speed spin too, and cloths come out of it less wrinkled than with the FLer. Maybe the wash action also has some effect. As for the detergent, I used All Small and Mighty Free and Clear HE detergent in three different machines, my old Kenmore TLer, my Bosch 500, and my Cabrio. I used the same amount of fabric softener in each machine. They were in the same location so the water would be the same. The only difference was the machine itself. Wait, and the number of rinses, even with minimal detergent, I had to use more rinses to remove the detergent in the 500. But rinses should not effect the fabric softener if it is added to the final rinse. Cloths never came out as soft in the front loader, and sheets and towels, especially towels, were rough and stiff, not soft and fluffy. It has to have something to do with front loaders. Could higher wash temp make towels stiff? I used hot water in the FLer and other machines. In the old Kenmore it was probably cooler, but I think hot would be the same based on incoming water temp. Even if the 500 was boosting the temp somehow on hot (which I don't remember it doing) I have raised the temp on my water heater twenty degrees since I got the cabrio. I did not realize it was still set at a lower temp from when my son was young. Water heats up much quicker and lasts longer now! So I have washed towels in the Cabrio at the old lower hot and the new higher hot. There was no effect on the towels, they still come out fluffy and soft, so I don't think it is the water temp.

I don't find a model SDGG2606AWW, but I do find SDG2606AWW. Gas dryers are outside my experience, but a non-heat situation when the unit still otherwise runs probably is related to the gas burner. Could be a bad igniter, flame sensor, or gas valve. There are two different burner assemblies for this model, depending on whether the unit in question is Series 16 or not. Parts are available for both types. Dryers are much more mechanically simple than washers, although gas models are a little more complex than electric. I would have it repaired.

If you still are unsure of what to get, some really good resources are youtube and expotv. With youtube you can see many brands in action and expotv has people who give video reviews. You can also find many written reviews by typing the name of the make and model of a machine followed with the word review in an internet search. For example, "Kenmore Top Load washing machine reviews", without the quotes. Tons of links will pop up. I hope this helps you and anyone else who finds themselves in this situation in the future. It helps me a lot when I need info about anything.
