Having gone through a similar decision process, I¹d make only these suggestions:
1. I built all of mine (K3, KX3, KAT500, KPA500, and P3) from kits. Not to save a few bucks - though it did that - but to have a feel for what was in the box in case I ever needed to go into them. Building them was enjoyable and feasible, even - as someone else once said on this list - for a lawyer. 2. Both the K3 and the KX3 include pretty much all the options, with three exceptions - I don¹t operate on 2M, I didn¹t think the TXCO would be useful, and I didn¹t do the voice recorder since I operate exclusively CW. For that reason my filter set includes the 6 Khz AM (for SW general coverage), the 2.8 for SSB in case I ever try that (though I haven¹t done it yet in the 56 years I¹ve been licensed) or if I ever want to sell the rig, and then the narrowest three for CW. 3. I bought the 8-pole filters, and have no excuse or reason for doing so. Also got the same five for the sub receiver as for the main. Again I can¹t tell you why. Seemed like a good idea at the time and I haven¹t regretted it yet. Buying 8-poles does save some time later in configuring for offsets, but I doubt that amounts to much. 4. What I would suggest is thinking about buying at the outset whatever filters you¹ll eventually want in the sub receiver. Installing the sub into the K3 was the hardest part of the entire build - requires fingers more agile than mine, though I eventually got it done. It took a couple of hours and several tries including unbuilding large sections when stuff got dropped and lost in the innards . . . As I remember, to install an additional filter in the sub receiver requires removing it entirely, and reinstalling. Life is too short for that; there are pileups to pierce.
