In many cases, you really get out of a gi what you put into it.
One thing that everybody probably knows, but should be said anyway, is that the quality of your gi will not at all make you a better or worse grappler. I've run the gamut on cheap to expensive gis in my time, and I can honestly say that the quality of the gi did not make a difference in my ability.
Now keeping in mind, I did do research on all of the more expensive gis that I've bought, and as a result never owned an expensive gi that turned out to be low quality. I've used an absolute no-name brand at the start, moved through Atama and Koral, and as other brands started to exist, tried some of them. There are noticeable differences in quality in those brands and those reflect shelf life.
Personally, I wear two brands of gi for training and for competing. Fushida is a fantastic gi company, but my go-to as of late is Origin. Fushida is considerably less expensive, but Origin's fit and quality make them my personal favorite (plus, they make their gis in the US). My Fushida and Origin gis both have so far lasted me several years and they don't appear to be anywhere near their last legs.
With more expensive gis, as long as you research them and make sure that they're quality, they will last your years if you take care of it. The cheaper ones will eventually fall apart, often in short order. I've had a cheaper gi last me literally less than a year, but some of my higher quality gis have lasted me 4, 5 or 6 years and they're still going strong.
It's best to do your research. Atama makes good gis, but they aren't reinforced as much as some of the others are. My Atama lasted 3 years. Kingz makes quality gis as well, though I don't own one. Gorilla Fight Wear is also good. Origin, my favorite, is a premium-priced gi, but I've had my first one for 4 years and it's still going strong. And Fushida also have very high quality gis and the two that I own, 3 and 4 years old, are also going strong.
I would recommend getting a better quality gi than one that is $65. I would recommend two, or three, with a higher weave count (think Dragonweave, Gold weave, or a simple double weave) and strong, reinforced pants. Two or three of those, with good washing, will cost you less in the long term and can fit very easily and quickly into your rotation.
