I've been collecting for about 25 yrs, I know enough to know I paid substantially less than what it's worth. I have not added neon to a sign before, just curious to know if the value would be worth the expense. If you must know I paid $350. I try not to go by the crazy prices on eBay for values. Thought someone would be kind enough to assist. What you pay for something is not always the value, however, I am quite happy with the purchase.
