Like LDF, I'd recommend that with 10k I think you'd be better off going to Quinn, Irish Life, etc. and buy the most diversified unit funds you can get. I bought a bunch of ETFs through a broker years ago and since then I've spent too much time filling out weird UCIT tax forms and the like. I haven't analysed it fully but I'm not sure it's been worth it in terms of my time.
Unless you're talking about at least 50k, personally I'd go for unit funds with the lowest charges and bid/offer spread. If your investment subsequently grows or you've a big additional investment, then you could think of switching to investing in ETFs directly. But if you do so, be prepared to spend a lot of time (or pay an accountant) to figure out all the tax implications.
