Advice on investing in English 151

Hi all!

I’m a new collector to the scene for the past few months and I’m totally gutted I missed the 151 set. I have managed to pick up a couple of booster bundles at a decent price but it got me thinking.

I would love to buy an ETB around £150 on eBay currently and probably a UPC to keep sealed for my collection. I just worry if I don’t act prices will continue to rise and I think it’s unlikely a reprint will happen for these 2 products. I will do my best to get some blooming waters from Costco when that arrives but think they may be a bloodbath. Is it a good time to invest in these original 151 products?

Edit: I have registered for 151 bundles on Amazon but not too hopeful I will get an invite for that

2nd Edit: shouldn’t have said it’s an investment. I just meant I want to add some to my collection before they go up even more
