I sold my 19" x 13" Canon ink-jet printer years ago. Although ink-jet printing is very convenient, tons of fun and produces gorgeous enlargements, it costs a fortune for the paper and inks. After trying a number of print services, I now use Costco for enlargements in the 7" x 5" to 18" x 12" range. The print quality at Costco is the best of all the services I've tried and it's only $3 for a 18" x 12". This is an amazing deal. The cost per enlargement is less expensive than printing at home without the hassle of 'clogged heads', banding, print head cleaning, etc. With Costco I can upload from home and pick them up when I go grocery shopping. Perfect color and an archival quality photographic print.
I frame my Costco 18" x 12"'s in a black Ikea Ribba frame ($15.) The Ribba frame includes a matt and glass. The frame is solid wood and the glass is glass (not plastic.) The matt opening is 15 4/3" x 11 3/4" - so the Costco prints fit perfectly with a little room for cropping on long axis. So, for about $18 I have a framed 18" x 12" photo. I'm pretty proud of this little system - I have about 50 prints on my walls using this combo (Costco print + Ikea frame.)
