Default Need advice: 99 Katana 600, bad carb with TPS sensor

Hey all. It's been a long time since my last post. Long story short, I've been trying for over a year (very casually) to get the bike up and running. I knew it was vacuum and carb related in my diagnoses. Did a rebuild with OEM kit on the carbs, but the carbs got damaged while off the bike. (Dropped on accident)

On the rightmost carb (The one with the TPS) the TPS sensor, and mounting screw holes were damaged and are unusable. There also was a minor spot where part of the fuel /air flow channel was damaged (See pictures). I patched the exposed flow area carefully, but the TPS mounting is totally unusable. I got the bike up and running but it's just rough constantly no matter what I do. I've eliminated the vacuum leak at the intake boots. It's a bish to start, and hard to keep running, and in general, its not fun to ride in the current state.

I decided to take it to a shop, pay someone to diagnose and fix the issue. They have come back and said the patch and TPS issue is the actual issue as the rebuild job looked good and carbs appear clean inside. That right side carb is damaged and in their opinion not fixable. But they can't get a new single carb, only the whole rack/set.

I'm not willing to put 700 bucks into new carbs at this point, so looking for some advice on should I buy a used set off eBay and have them use them or just post the bike for sale and cut my losses? I only ever really wanted to spend about 500+/- to get the bike back running. Its the major cost to replace the carbs that are making me think, sell and cut my losses. I'm just hesitant cause everyone says the bikes in great shape for being a 99, she just runs for pot. Does anyone have any advice or thought/ideas on what I could do? The one rebuild I did took ages, and I don't have a place to do it at anymore honestly. Is she really worth putting approx 600-800 dollars into to get running?
