I had a near-deal with him at the end of the year that sounds kind of similar. I had a bat for sale. He said he only had so much in PayPal and asked if it was enough. Told him that I'd take it and gave him PP addy.
A week later he said he was having issues with PP and he'd get it sent ASAP. Another couple days later "unexpected bills came up" and he only had most of it in his account. Asked if I'd take that now ("before he spent it on something else") and the rest when he got it because he really wanted to swing it over the weekend. I told him that I'd rather wait 'til he had the full amount. Never heard back from him.
Hope he's just a little dis-organized and you get the rest of your money. Doesn't look like he's been on since early March.
The cell I have for him is 956-561-7292, if it's different than what he gave you.
