And it's too bad the things are so stupid to ship Gilrock, or I would send you a TV.
Are there no curbside/dumpster/craigslist tubes in your neighborhood any longer?
I don't know where Gilrock is but around the NYC area they are tough to come by. We have a recycling place in town but you aren't allowed to take - I've been yelled at plenty of times rummaging through the shipping container where they put everything and even then I almost never see tubes (the screens are mostly old LCD TVs). Maybe I'm just not getting lucky though
There's a bunch of $50 arcade monitors here:

And a TV with component inputs here:
https://newyork.craigslist.org/wch/ele/d/tarrytown-philips-crt-tv-sony/7290344787.html
The search terms I use are "crt tv" "crt monitor" "not a flat screen" "trinitron" "tube tv" "arcade monitor"
Component TV + GreenAntz RGB/VGA to component transcoder (still only
US$60 including shipping to USA) and you're in business.
If you find a composite input TV and it can't be RGB modded, good chance you can easily component-mod it. Component modding is often easier as it can use direct inputs to the jungle chip, rather than having to go in via OSD.
There are four of these 20" TVs I know how to component mod, which are available "new" in box for about US$65. They are locally assembled in Thailand and have new electronics "China TV" chassis + recycled tubes. Wondering if it is worth buying them up and doing a production run of 20" arcade cabs. That'd make the build thread more interesting. I love the 20" size tubes for cabs.
On the other hand, last week I found 2 local 20" TVs, one Sanyo with component inputs already and a TCL with composite. I haven't had a look inside the TCL yet, but hopeful that can be component modded too. TCL might have vertical deflection issues as image looked a bit squished (should be able to fix that, fingers crossed X). Paid about US$25 in local monopoly money for both.
There are still a lot of CRTs floating around in Thailand, to be expected as they are still being used more than in highly developed economies. Greater economic stratification too - richer people getting rid of old stuff, but poorer people still using it. Anyway, good to have TVs easily available because finding arcade monitors in Thailand is quite hard.
