As stated, you can also get a cheapo meter. Just get calibration solution to check it.
The key is storing your meter properly. I always store my pH pen in 4.01ph solution. It never dries out(which is the #1 reasons pens go bad)and always is cal'd
Careful dunking those one's. They call them waterproof, but they're not. The spec says you can hose them down, but the screens often leak. My LHS was asking the price of a tip, for the whole meter.
Amazon have the usual $10 bargain looking meters, but seem to want $60 for the $30 stuff sold on eBay. It's the bigger is better attitude. Where the most expensive of 3 items, is thought to be the best. I would be careful there.
For years I have wanted to try an Omega meter, but mine just won't break. Omega are not a hydro brand. The better meter is £130 and new tips are £50. It's a proper long glass thing though. It's real. With 0.8 second response time. It's not the one I need though. £90 gets the typical meter that can be held underwater, a full meter deep for half hour. New tip £35. Plastics that look like hdpe, not something that will either melt or shatter.
The £130 meter has an rs232 socket, and about £300 gets a data logging meter.
The £90 meter has been on that site about a decade that I know of. It can't be bad. But what I really like about there meters... AAA batteries. Even the £40 meter uses them.
8oz of fluid would outlast me lol
