I would much prefer a eu proxy even if price would be the same or even more. I'd happily pay a higher price for the certainty.
If it take longer, that's irrelevant.
Some important factors
1. In some countries, customs are a nightmare and it can be delayed for a long time.
2. Random element of customs. Customs usually has extra fees. So they basically charge you a fee for writing you a ticket
3. I know the price 100% advance.
4. Shipping is much cheaper inside europe
5. I also think you will get more orders. Many people will feel more comfortable ordering from a european store.
The same debate has been iterated with GMK drops. EU people will always prefer the stability of a eu proxy running stuff. I would probably not bought solarized dark if mykeyboard didnt proxied it. I skipped oblivion for the same reason.
