I can emphasise with the OP......
6 months ago I had a little money spare so decided to upgrade from my LMII. Got a LM III and was underwhelmed, it was virtually identical, just newer. So started with a little bit of GAS and have just traded the LMIII on here for a TTE RJ 500 head. Now this does sound and look different and my 210T cab looks a bit weird under such a (relatively) wide head. So now I've just traded up to a RJ 15" cab to go with the RJ head. Trouble is no tuner lineout on the head out so have bought a Korg Pitchblack. for tuning....
It's been fun researching and have had 4 new amp, amp cover, cab, and tuner days... In total spent £400 on this total upgrade for something heavier and wider than what I started with! Could have bought one of those GB combos for that money and kept my existing rig!
