Easy,
L-200 is by far the most common of the two at Venezuelan and Colombian exporters.

Polkadot,
This is because L 128, L 200, the blue Panaque, L 52, and all of the other upper Orinoco loricariids have to be transported to Bogota by air. There is a dirt road that goes across the llanos to Puerto Carreno (which is the largest Orinoco town), but it can only be traveled a few months out of the year in the dry season and, even then, is a 35 hour dangerous drive through guerrilla held territory in a 4X4. Most P. nigrolineatus (along with Farlowella vittata, LDA 68, P. maccus, Ancistrus trilineatus, etc) come from Villavicencio in the llanos which is connected to Bogota by good road. The government is now escorting conveys of civilians (to promote tourism) with armored vehicles and helicopter gunships which has made travel between the Villavicencio and Bogota more frequent (the conveys travel almost every week). So yes, in the end llanos fishes cost much less than Orinoco fishes. In Bogota large (6 inch) L 200 sell for about US $6.50 each while the same size P. nigrolineatus would sell for less than US $3.00.
