Allison, I'm not Ted but I think I'm the only one who brought up LDMOS in this thread.
I'm looking at ways to fit AFM907NT1 in QMX. It costs 2-3 bucks a piece depending on where and how many you buy. NXP and ST offer several other options in DFN, PLD-1.5W and SOT-89 packages. DFN and PLD have much better thermal characteristics than SOT-89, although the latter is much better than TO-92. Obviously, not everyone is comfortable with hand soldering these packages, so for kits, TO-92 is a good choice. But we can do our mods at our own risk. I have some idea of mounting AFM907NT1 dead bug style on QMX board. I'll get into detail when I have something to show.
To meet the QMX spec, AFM907NT1 is an overkill, but I'm ok with that. It's made for 7-8W output at 7.4V supply, so with a push-pull, it can be used up to 15W range... but I'll be using it very conservatively.
Now, using AFM907NT1 in HF range is an amateur job because the spec sheet says it's a V/UHF device. But usually these specs are decided based on the device's internal impedance characteristics and risk of instability; discrete devices usually work at lower freq as long as care is taken in matching and stability criteria.
