Another nonsense post to have to deal with...
Affordable and Ham Radio - the two phrases usually don't mix.
One of the neatest things about ham radio is, it can be whatever you want it to be, and cost whatever you want it to cost.
My advice would be for you to get a job or a second job - such as Burger King or McDonalds and save your money for a couple of months and apply that money towards one really good all around radio and forget about trying to scab together something on a budget.
While the idea of a second job isn't necessarily out of the question, why discourage someone from finding one of the many, many bargains there are to be had?
By the time you buy a radio or two, the coax for each antenna, a antenna tuner / tuners, a couple of really good antenna's. A tower or mast, all the grounding, a power supply - you will have just as much or even more into it then if you just went out and bought a used Icom 746 Pro II....
You grossly over complicate the relative simplicity it takes to actually get a station on the air. Yes, all those accessories can cost a lot of money, but they're not all necessary to get a modest station going. My first ham rig was a used transceiver, my first antenna was a dipole strung between the peaks of the roof, and my first contact was to Indonesia.
Too many new hams gets into a hurry to get on the air and in their haste - wastes good money after bad on radios that doesn't work or works marginally. They usually loose interest around about the time it costs more to buy the antenna then it does to buy the radio.
There is an element of truth to this, but wouldn't it be more productive to help the new comer in learning how to select a good used rig, and how to assemble modest, but effective, antennas, as opposed to suggesting he get another job and wait it out until he can buy the ultimate DX station?
Every day I hear a half a dozen people come on the repeater system that says - I bought this old radio 20 years ago and I charged the battery and wanted to see if it still worked.
The truth is - they bought it when there was people on the repeaters and when the people all went to cell phones and the internet - the 2 meters was forgotten.
Maybe the truth is, they have a 20 year old radio that they just wanted to see if it works? I have a garage full of old radios, and every once in a while, I'm inspired to fire one up and see if it still works.
I would suggest that you buy the same radio that I bought. Yaesu Ft 8900R
Quad Bander - 440, 2 meters, 6 meters, 10 meters - all in one radio.
While that's a worthy radio, you fail to take into account something rather critical here. The OP specifically asked about 6 and 10 meters, and mentioned he was a tech class licensee. The technician class license has limited 10 meter privileges:
28.000-28.300 MHz: CW, RTTY/Data--Maximum power 200 watts PEP
28.300-28.500 MHz: CW, Phone--Maximum power 200 watts PEP
Note that the FT8900 is not SSB or CW capable, and technicians do not have privileges in the 10 meter FM portion of the band, making the FT8900 a dubious choice, given the interests expressed by the OP.
