I have an FLM CP30-S4 II tripod I might be willing to part with for $300, you would just need to add a head or leveling base. Are you looking for something with a platform or do you want a vertical extension?
Looking for one with a vertical extension, however I am a total novice with tripods. Are there any cons to having an extension vs platform? Or just personal preference?
Vertical extension gives you the quick elevation without having to move/adjust the legs which is nice for hunting and glassing. Something with a platform/bowl/leveling base is going to be more stable and is typically what PRS shooters gravitate towards. Personal preference is definitely a factor. I have both and sort of overlap their uses. For your intended purpose I would say go for a vertical extension.
If no one has anything, the SLIK brand offerings are supposed to be a good value for the money.
I've got a feisol carbon fiber I'd let go. Also has the long extension tube as well as the short one. Desmond db55 ball head. Used 2 seasons in prs matches. Not perfect but not hurt either. I think it's the 3372 model. I'll get you some pics if interested. $435 for everything.
