All Myachis are retired after a few months so any Myachi you acquire will be rare within a few years of purchase. To find rare Myachis you are best off checking online Myachi forums where long time collectors will often offer Myachis for sale or trade. There are usually a few rare sacks on popular auction sites as well.
The best place to find the newest Myachis is the official myachi website, though there are a number of online retailers that carry the product and may have older series. You can also find Myachi in a number of stores across the country. If you search "Myachi Locator" on googlemaps you will find an extensive and up to date list that shows the exact location of over 200 stores that carry Myachis all around the world.
Old school or rare Myachis are not available in stores or on most websites. Generally speaking, you will only find rares on auction sites such as ebay, though you can often find Myachi enthusiasts willing to sell or trade on the official myachi website or the official myachi forum.
Technically, there is no "least rare" Myachi, since all Myachis that are currently available on myachi.com have the same level of commonness, however, the most plentiful Myachi is the Sobe '02, of which 100,000 were made. Since this was last manufactured in 2002 it has since become relatively rare despite this high number. The Black Butter is also often referred to as the "Most Common" Myachi, since it was made in greater numbers than any other series (non-promotional) sack. Again, since it was last released in 2008, it should no longer be considered the "Least Rare" either. The best answer to your question is that any sack offered in the 4.5 series is currently the "Least Rare".
Myachis are rectangular bags of fabric filled with sand (called "Secret Sauce" by the company). They are made from a number of different fabrics, but the most popular are corduroy, microsuede, denim and velvet.
The Guatemalan wallet is considered the rarest of all Myachis, though there is no definitive proof that this sack still exists. The rarest Myachi that is known to exist is the prototype sack, the "Silver Surfer". Only 3 were made and that was in 1999.
The MSRP (Manufacturer's suggested retail price) of a Myachi is $6.99 in the most common packaging. Myachis also come in a wide range of lisenced properties such as NYC or NBA sacks, which can cost $7.99, $8.99 or $9.99.
