XML feed creation

i want to create an xm lfeed using YGL list.YGL api return only 100 result at a time.But I need to display all result .Total count of YGL rental search result is 2026.Two solutions I found is,

1.Using cron and fetch data from YGL and insert it in to Database. Then fetch data from Database and show it an xmlfeed.
the second way is,
2.Searches based on locations  then stitch the results together to generate the xml feeds.

But I can't take a good decision.Which method is better?using cron or location search?Is search take too much time?Any one please help me
