Cannot recommend highly enough. Have purchased several pens from them. They have a great variety, even better instructional / informational articles & YouTube channel, and superb customer service. Their prices are also about as good as you're going to get.
Have only once ever had one pen show up damaged, and the amount of patience and care they exhibited - even leaving a custom note in my replacement assuring me they had checked the part creating an issue in the first pen (noting that everything worked flawlessly) - was beyond what I have seen at pretty much any company - regardless of what they sold.
Watch their videos; see how much they care; and order from them. You won't regret it.
