A friend of mine went to the Grafton, MA flea market and when leaving saw a LGB train set at a table and for only $15.
It was a broken 0-4-0 engine (most likely the 20232) and non powered tender plus a beat up tank car and caboose all 4 axle equipment.
He hesitated for 10 minutes and bought it. then the seller asked if he would also like the power pack the LGB 1 amp 50081 no charge.
I let my friend know the power pack alone was a bargain at $15.
