    I have been looking for special power rectifier switching diodes that none of the many companies offering electronic components had not listed at all, or were showing several weeks, even months of lead time.
    When I asked Allelco for a quote, even for a diode they’d not listed, I got an instant response and a competitive quote for the parts not listed on their website.
    Allelco was accommodating regarding the payment method as well as the courier.
    On top, the sales person I was dealing with was very pleasant and courteous. Overall a good experience, will ask them first for everything electronic.
