Thinking about trying digital fpv

I was into fpv back around 2016-2018 but ended up taking a few year break. I'm getting back into it now and really like the looks of digital but am not really sure where to start.

Currently everything I own is analog. My headset is a pair of original Fatshark HDO's with a true-d v3 furious module in it.

I did a bit of research and it looks like my options for getting into digital are the following:

I could buy a Walksnail module to make my fatshark hdo's compatible with walksnail VTX's. This looks like it'd cost about $220.

I could buy HDZero goggles which seems like would be a straight upgrade to my fatsharks as they are better quality and work for digital and analog. This would cost about $600 and seems like the most expensive. Not sure if this is worth it till I know I like digital.

Lastly, I could buy a pair of secondhand DJI FPV Goggles V2 for $250-300 and be able to use dji VTX's. But I guess the downside to that would be I'd be limited to only using DJI VTX products?

I'm just hoping you all can give me some advice in which direction they think I should go as either of these options are decently expensive.
