I am not a fan of the inflated retail prices either.
If there is a model I really like, I'll go second-hand and look for models and brands on eBay, Facebook Marketplace and the other App options. It takes more diligence and awareness to monitor, but when the items I want are listed, I make my offer or place my max bid immediately.
For example, I prefer "made in USA" Tumi products, pre-2001. I'll keep an eye out at second-hand stores, eBay and the like and typically purchase bags, at a fraction of what they sold for full retail. That way, I get the specific era Tumi product I want, at the price point that has value to me.
Same goes for RIMOWA, there are plenty of second hand stores throughout Europe that sell vintage RIMOWA, and LV luggage.
Just like any purchase, it all depends on your personal preferences.
If you prefer hard-side, aluminum luggage, and price is an important metric, I would suggest Away luggage.
If Tumi's prices are outside your price range, go down one label in the Samsonite portfolio and check out their range of products.
The options are endless, and with so many subjective metrics that every consumer has, there is never a blanker answer suitable for everyone.
