the Romanian AK's are the least expensive,. they do not have the best fit & finsh most of the time but i never had any problems with mine.
the Yugo's i've hade where pretty well built,. but i did not care for the underfolder and aold it and picked up a fixed stock model later on.
i love my milled guns Arsenal SA-M5 & SLR-100H (Vector) they are the smoothest and best shooting AK's i have
for your first i would say go with a Vector AK from Atlanticfirearms.com
they have a great selection good prices, and are very easy to deal with.
i really can not make any further recomendations until i know more about exactly what you are looking for.
hope it helps
